Mix 1oz lemon icing fruit to every pound of glaze. Reserve. Make up scones according to manufacturer’s directions, adding in 20% frozen blueberries in the last 30 seconds of mixing. Divide dough into 2 pound 3oz duffs. Shape into a discs about 10 inches across, taking care to make sure the dough thickness is even. Brush liberally with egg wash and sprinkle with sanding sugar. Cut each duff into 8 even wedges. Each wedge should weigh about 4.4oz. Place prepared wedges on parchment lined sheet trays, double pan each sheet tray to prevent overbrowning on the bottoms. Bake at 365 ͦF for 15-18 minutes or until scones are a rich golden brown. Let cool completely and drizzle with prepared lemon glaze.
